DNV GL has presented Hyundai Heavy Industries (HHI) with a general approval for ship application (GASA) for a new concept of very large crude carriers (VLCCs) with a centreline oil-tight longitudinal bulkhead. The new design will reduce potential damage and operational risk by featuring a simpler structural arrangement, loading patterns and piping arrangements. Vidar Dolonen, DNV GL Regional Manager for Korea & Japan, delivered the certificate to Seung Ho Jeon, Executive Vice President of HHI at the shipyard group headquarters in Seoul.
